This policy covers the Knitted app for iPhone and Android and these pages. "Knitted", "we", and "us" mean Krux Lab LLC. "You" means the person using Knitted.

01What Knitted collects

What you tell Knitted

Your account

After you buy Knitted, you sign in with Apple or Google so your journey is saved to an account. Apple or Google gives us an ID for you, which is how we recognize your account. They may also share your email address; we don't store it.

Purchases

You pay through the App Store, Google Play, or our web checkout. We see what you bought and when, and whether it's active. We never see your card details.

How the app is used

Knitted has no separate analytics tool. To learn whether setup and the paywall work, our purchase provider, RevenueCat, keeps a few simple details with your purchase record: how far you got through setup, how long it took, which paywall you saw, and, until you buy, where you are (for example, "pregnant", the trimester, or expecting twins) so the right plans are shown. They never include names, dates, notes, or what you log.

Where you found Knitted

If you open Knitted from one of our links, we keep the campaign it came from (for example, a newsletter or an ad). On iPhone, we may also receive the Apple Search Ads campaign that led to the download.

Device and diagnostic information

Like most apps, Knitted's services see basic technical details: your device model, operating system, app version, IP address, device identifiers used for purchases, and whether the app failed to start. Our servers keep short-lived logs to keep the service running and secure.

02What stays on your phone

Health app and wearable readings are never used for ads and are never used to estimate your fertile window.

03How we use it

We don't sell your information, use it for advertising, or build advertising profiles.

04Who helps us run Knitted

A few companies process information on our behalf, under contracts that limit what they can do with it. Each sees only what its job needs:

CompanyWhat it does, and what it receives
CloudflareHosts our servers and stores your account, saved journey, and photos.
RevenueCatManages purchases and subscriptions. Receives your Knitted account ID, purchase history, device identifiers, the campaign you came from, your progress through setup, and your journey stage (such as pregnant, the trimester, or expecting twins).
ExpoDelivers app updates and reports when an update fails to start.
Apple and GoogleSign-in, app stores and payments, and (only if you allow it) Apple Health or Health Connect on your phone.
OuraOnly if you connect it, as described in section 2.

We also share information when the law requires it, sharing only what's required, and if Krux Lab or Knitted is ever sold or merged, in which case this policy continues to apply to your information.

05Advertising

Knitted has no ads. We never send your health information or anything you log to advertising networks.

We do advertise Knitted. If you buy Knitted through our website after tapping one of our ads, the ad platform may be told that a purchase happened, so we can see which ads work. That never includes anything you track.

06Keeping it safe

To be straight with you: Knitted is not end-to-end encrypted. Our systems can technically read what's stored in your account, and we limit that access to running and protecting the service. No system is perfectly secure; if a breach affects you, we'll tell you as the law requires.

07How long we keep it

08Your choices

09Your rights

Wherever you live, you can ask us to show you, correct, export, or delete your information. Depending on where you live (for example the EU, UK, California, Colorado, Connecticut, Virginia, Washington, or Nevada), you may also have the right to:

Email dev@kruxlab.com. We'll confirm the request comes from you, then answer within 30 days, or sooner if the law requires; complex requests may take up to 45 days more, and we'll tell you if so. To appeal a decision, reply to our answer with "Appeal" in the subject. An authorized agent can ask on your behalf with your written permission.

EU and UK

Krux Lab LLC is the controller of your information. We rely on: providing the app you asked for (contract); your explicit consent for health information, which you can withdraw by deleting your account; and our legitimate interests in keeping Knitted secure and understanding whether setup and purchases work (which you can object to by emailing us).

10Consumer health data

This section is our Consumer Health Data Privacy Policy under Washington's My Health My Data Act, Nevada's consumer health data law, and similar laws. It covers information that identifies you and is about your physical health, including your reproductive health.

11Children

Knitted is for adults. It isn't meant for children, and we don't knowingly collect information from anyone under 13 (or the age required where you live). Information about your baby or child is entered by you as their parent; you can change or delete it any time. If you believe a child has given us information, email us and we'll delete it.

12Where it's stored

Krux Lab is in the United States, and our providers may process information in the United States and other countries. Where the law requires it, we use recognized safeguards for these transfers.

13Changes

If we change this policy, we'll update the date at the top. If a change affects how we use information you've already given us, we'll tell you in the app before it takes effect and, where the law requires, ask for your consent.
